I need some advice on sticking metal parts (Aluminum and steel) to wood. These parts will be under some stress, so I want to make sure I use the right adhesive. I’ve been checking out two options: G-Flex and 3M DP420/460. The great thing about G-Flex is that it’s cheaper, and if I go with the 650 version, I can even reinforce fiberglass with it. On the other hand, DP420/460 is probably stronger, but it’s a bit pricey and you need an applicator, which is a bit of a hassle.

Have you or anyone else compared the strength of these two adhesives? Also, do you happen to know any clever tricks for using DP420/460 without an applicator?
